Muay Thai and BJJ are probably the best two piece combo out of any two martial arts.

Muay Thai gives quite a lot of dominance standing over almost all other martial arts (except possibly boxing, but boxers only use fists).

BJJ gives dominance when on the floor over everything, as well as making up for the lack of grappling in BJJ.

They are basically opposites in martial arts terms.

I'm starting both Muay Thai and BJJ. I am 15 and quite for but not strong, Muay Thai runs twice a weak for an hour. And BBJ once. There's a gym there aswell, Is that enough lessons?

And what will be the pros and cons of mt and bjj?

Thanks
